Cruising US Inland Rivers
America's Great Loop runs through a river system no coastal chart covers: the Mississippi, Ohio, Tennessee, Cumberland and the Illinois Waterway, threaded with locks, dams, and a barge traffic culture all its own. This region uses survey-grade inland ENC, with the locks, dams, fixed-bridge clearances and dredged channels that Loopers actually need — the one chart set built for the rivers, not adapted from the sea.

Questions
Why a separate chart for the rivers?
Coastal charts don't cover the inland river system. This uses survey-grade inland ENC with the locks, dams and fixed-bridge clearances the Great Loop needs.
Are locks and dams shown?
Yes — locks, dams, dredged channels and bridge clearances from the inland ENC are included, with depth-aware routing for the river depths.
Does it cover the whole Great Loop river section?
It covers the inland river leg — Mississippi, Ohio, Tennessee, Cumberland and the Illinois Waterway. Pair it with the US East Coast & ICW region for the coastal half of the Loop.
